Five minutes of audio from the 911 call made Dec. 29 from Hacienda Healthcare were released Friday, The Associated Press reported. The call spurred Phoenix police to begin a sexual assault investigation.

Police have released audio of the 911 call a nurse made after an incapacitated woman at a care facility gave birth. The nurse said staff didn't know the woman was pregnant.

The 29-year-old woman has been incapacitated since a near-drowning incident when she was 2 years old and has been a patient at Hacienda Healthcare since she was 3. Investigators are trying to determine who impregnated her.

Phoenix police Sgt. Tommy Thompson told KPHO-TVthat DNA was gathered from "a large number of individuals."

The revelation that a woman in a vegetative state was raped inside a care facility has horrified many, the AP reported. The Hacienda Healthcare CEO resigned earlier this week, and the facility announced new safety measures, including not allowing male staff members to enter the rooms of female patients without a female staff member present.

The woman’s familymembers, who are members of the San Carlos Apache tribe, released a statement through their attorney saying theyare “outraged, traumatized and in shock by the abuse and neglect of their daughter at Hacienda Healthcare,” and that theyare “not emotionally ready to make a public statement,” KPHO-TV reported.
